Don’t be that person who doesn’t pay attention to the little sticker in the corner of the windshield that car places put on there for the express purpose of making it stupidly easy to know when to take your car in for an oil change. Otherwise you’re going to be stuck being that person who needs to count on their roommates and friends for rides while you wait for payday so you can get your stupid car fixed because the oil situation got out of hand and caused problems.
Update: Sometimes if you’re that person, your roommates will want to play video games and not watch the clock to see when it’s time to pick you up from work at night, so they will come get your keys and change the oil in your car and fix the problems that it caused enough that your car is driveable for the time being. But then again they also might want to play video games and not watch the clock to see when it’s time to pick you up from work at night, so they will leave you stranded at work, so I wouldn’t count on that. Thanks guys.
